Makes sense for the PGC to try this since it hasn't worked anywhere else.
All the PGC has been successful at so far is deterring hunters from hunting in areas where they should be.
What do mean it hasn't worked anywhere else? If you mean they haven't eradicated CWD by extensive culling you are correct. But there is no way of knowing how much more wide spread CWD would have bene in the areas they had major culling programs had they not reduced the herds in those areas.
In fact if you did some research on the subject you would find that Illinois was pretty darn successful it halting the spread there with massive culling. So much so in fact that neighboring Wisconsin is re-evaluating their prior decision to back off on their massive herd reduction. WCD is spreading in leaps and bounds there again and Wisconsin has recently proclaimed they made a mistake by backing off due to the public and political pressure they were receiving to do so.
